For most voters, their decision to vote for President Obama or Mitt Romney wasn’t a last-minute thing. But four percent (4%) of Likely U.S. Voters finally made up their minds on Election Day.

A new Rasmussen Reports national telephone survey finds that 70% made up their minds about how to vote more than a month ago, while another 18% decided within the last month.

But five percent (5%) decided within the last week and three percent (3%) within the last few days. Combined with the four percent (4%) who reached a final decision at the very last minute, this means 12% of voters decided whom to vote for in the last seven days of the race.

The survey of 1,000 Likely Voters was conducted on November 6, 2012 by Rasmussen Reports. The margin of sampling error is +/- 3 percentage points with a 95% level of confidence. Field work for all Rasmussen Reports surveys is conducted by Pulse Opinion Research, LLC. See methodology.
